When I read the forums about border crossings and they list what you should do and how you should act just to get across the border like don't wear sun glasses, don't smile, don't say this and don't say that, and god for bid don't look them in the eye etc etc.....reminds me of the horror stories of crossing the borders during world war II.
Do people cross back and forth without a problem yes. But for me hearing the stories like this one and MANY others just convinces me that it is not worth the chance of being the one selected out for this type of abuse by ANY government north or south.
I travel with a bag of meds for my dog that has seizures. I couldn't even fathom what one of these crazy border guards would do with that on board my MH. He can't live without them and I can't cross a border with them. What does that tell you about the governments north and south now a days?
The OP's experience could happen to 'anyone' of us and IMHO he shouldn't be slammed for it just because others have flown thru boarder crossings without incidence.
I find it very disturbing that honest citizens of any country are 'judged' and 'abused' when crossing borders solely because of what criminal drug dealers do.
